Yes, Filsuvez can be covered by Blue Cross Blue Shield of Illinois (BCBSIL), but requires prior authorization for all plan types. For Medicaid plans, it's listed as non-preferred with specialty pharmacy restrictions. Commercial and marketplace plans require individual verification. Your fastest path: Have your dermatologist submit a PA request with EB diagnosis confirmation, prior treatment history, and wound documentation through BCBSIL's provider portal. Start this process immediately—standard approvals take up to 15 days, and denials can be appealed within 180 days in Illinois.

  3. Include Specialty-Specific Information
    • Patient age (must be ≥6 months)
    • Confirmed EB subtype (COL7A1 for dystrophic, LAMA3/LAMB3/LAMC2 for junctional)
    • Wound characteristics (partial-thickness, 10-50 cm², present ≥3 weeks)
